PRESSURE-CONTROLLED MEANS FOR HYDROCARBON-BURNERS.

' To all whom it may concern:

Be it known that I, CHRISTIAN O. BARION, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inPressure- Controlled Means for Hydrocarbon-Burners, of which thefollowing is a specification.

The hereinafter described invention relates to an improved pressurecontrolled means for regulating the flow of steam and oil to anysuitable type of hydrocarbon burners; the object of the invention beingthe production of automatically operated mechanism thrown into action byincreased and decreased, 2'. 6. variable pressures of the infiowingsteam in order to proportion the quantity of oil admitted to a pressurechamber in accordance with variation in the steam admitted thereto sothat the oil supply will remain constant with the inflowing steam,thereby maintaining under all work ing conditions of the hydrocarbonburner the proper admixture of oil and steam.

To comprehend the invention reference should be had to the accompanyingsheet of drawings, wherein is disclosed the invention as interposedbetween and connected with the steam supply pipes leading from the drumof a steam boiler, and the oil supply pipe leading from any suitablesource of oil supply, the steam andoil regulators and the pressurechamber with which the hydrocarbon burner connects being in verticalsection.

In the drawings, the numeral 1 is used to designate any well known formof a steam supply pipe for dry steam extended from the drum of a steamboiler, and connected to a valved-union 2, to which union is ati lator18, provided with a fixed vertically disposed diaphragm 18 which forms atachecl a pressure regulator 3 for controlling the action of the valve 4within the union. The valve 4 is a balanced one and movablelongitudinally within the valved union 2 for regulating the flow ofsteam from the supply pipe and through the port opening 5 into thepressure chamber 6 with which the union 2 is united at its upper end bymeans of a suitable connection 2. The valve 4 is provided with a stem 7which passes through a stuffing gland 8 within the regulator 3 and itsfree end is connected to a vertically disposed Specification of LettersPatent.

diaphragm 9, which is acted on by the pressure of a retained spring 10situated in the said regulator, the pressure of the spring against theface of the diaphragm being increased or decreased as desired by meansof the adjusting screw 11.

The steam pipe 12 leading direct from the drum of the steam boiler isconnected to the regulator 3 for the discharge of steam into the chamber12' in advance of the diaphragm 9, the pressure of which balancing thepressure of the spring 10 acting against the diaphragm 9 serves tomaintain the same in neutral position and the valve 4 balanced withinthe union 2 to maintain open the port 5 for the flow of steam into thepressure chamber 6, just so long as the pressure of the steam flowingtheret-hrough is sufficient to equalize the steam pressure within thechamber 12 of the regulator.

To the lower end of the pressure chamber 6 is united by a connection 6to a union 13 in which is a guide way 14: for a hollow cylindrical slidepiston 15, which piston is open at its inner end. This slide piston isprovided in its side wall with one or more angularly disposed orV-shaped cut out inwardly flared to form a tapered port 16 for the flowof pressure oil into and through the slide piston, so that as the pistonis moved inwardly the area of the passage for the oil flow through saidout rapidly increases, allowing a greater quantity of oil to flowupwardly through the piston and port 16 into the pressure chamber 6.VVithin the union 13 back of the slide piston is formed an oil chamber17, into which oil enters through the conduit 17'.

To the valved union 13 is attached a regusteam chamber 19, and to saiddiaphragm is secured in any suitable manner the rod 19 of the piston 15,the said stem passing through a stuffing gland 30. The piston 15 is heldupon the rod 19 as by suitable nuts 19 and 19 threaded to the rod 19'and engaging respectively opposite surfaces of the end of the piston.Back of the diaphragm 18 is located a spring 20' which acts thereon, thepressure of which is adjusted by the regulating screw 21. From thepressure chamber 6 steam is admitted into the steam chamber 19 of theregulator 18 by means of the direct by-pass connection 21. Oil underpressure is supplied to the union 13 by means of a supply pipe 22, whichleads from any suitable source of oil supply.

To the pressure chamber 6 is connected by a connection 22 a suitableform of hydrocarbon burner 23, the oil and steam being supplied theretounder pressure from the said pressure chamber 6.

At times it is desirable that the regulating means be so adjusted as tokeep a small flame burning within the furnace. For this purpose the oilsupply should not be entirely out off, and to accomplish this an adjustable stop 23 is provided, which screws in a plug 24: screwed intothe union 13, the said plug being protected by means of a cap 24 screwedupon the externally threaded circumference of the plug or boss 24.Vithin a central bore in the adjustable stop 23 is loosely extended theouter end of the piston rod 19, the position of the adjustable stop 23limiting the stroke of the said rod 19 and consequently the movement ofthe slide piston.

Under the described form of connections as the pressure of steam directfrom the boiler varies, a change of pressure in the presure chamber 12of the steam regulator 3 takes place, which variations in pressure causea shifting of the valve 4 and the piston 15 in order to regulate theflow of steam and oil into the pressure chamber 6 in accordance withsuch variations in the steam pressure of the boiler. For instance,presuming the steam regulator 8 to be adjusted to a hundred pound boilerpressure, and the oil regulator 18 adjusted to cooperate therewith undersuch an adjustment, if the steam pressure in the boiler rises above apressure of one hundred pounds, a corresponding increased steam pressuretakes place in the chamber 12 of the regulator 3, which acting againstthe diaphragm 12 and overcoming the resistance of the spring 10, forcesthe said diaphragm inwardly, which carries therewith the valve stem 7,moves the slide valve 4 to reduce the flow of steam into the pressurechamber 6, thereby reducing the steam pressure therein. As the pressurewithin thesaid pressure chamber is reduced, the pressure within thesteam chamber 19 of the oil regulator 18 drops, when the pressure of thespring 20 acting against the diaphragm 18 overcoming the reduced steampressure within the chamber 19 forces outwardly the said diaphragm 18,which carrying therewith the piston rod 19 moves the piston 15 to reducethe area of the port 16 and by so doing throttling the flow of pressureoil through the piston and port or conduit 16 into the pressure chamber6, thus proportioning the flow of oil to the flow of steam into the saidpressure chamber; conversely, if the steam pressure within the boilerdrops for any reason, the spring 10, of the steam regulator,overcomingthe pressure within the steam chamber 12,

forces outwardly the diaphragm 10, which,

through its connect-ion, moves the slide valve 1 to increase the flow ofsteam into the pressure chamber 6 and raises the pressure therein, whichincreased pressure is transmitted to the chamber 19 of the oil regulator18. This increased pressure overcoming the pressure of the spring 20forces inwardly the diaphragm 1,8 to move the slide piston 15 to exposean increased area of the port 16 for the admitting of an increased flowof the pressure oil through the said piston and the conduit 16 into thepressure chamher 6, thereby proportioning the oil flow proportionatelyto the increased steam pressure admitted into the said pressure chamber.The flow of steam and oil into the pres sure chamber is thusautomatically con trolled or regulated in accordance with either anincrease or decrease in the steam pressure of the steam boiler, therebyautois claimed as new and desired to be protected by Letters Patentis 1.
